DECnet Phase IV MIB Extensions
Status of this Memo
This memo is an extension to the SNMP MIB. This RFC specifies an IAB standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited.
Abstract
This memo defines a set of DECnet Phase IV extensions that have been created for the Internet MIB. When used in conjunction with the structure of management information (RFC 1155), the management information base for network management of TCP/IP-based internets (RFC 1213) and the Simple Network Management Protocol (RFC 1157), it will be possible to provide integrated network management of combined TCP/IP and DECnet Phase IV based internets. This document was produced by the DECnet Phase IV MIB working group of the Internet Engineering Task Force (IETF).
Contents
Introduction
With the adoption of The Simple Network Management Protocol (RFC 1157), the management information base for network management of TCP/IP-based internets (RFC 1213), and the structure of management information (RFC 1155), by the Internet, and a large number of vendor
implementations of these standards in commercially available products, it became possible to provide a higher level of effective network management in TCP/IP-based internets than previously available. With the growth in the use of these standards, network managers desired to use this environment as a base for providing integrated network management of multi-protocol networks.
DECnet Phase IV is one widely used protocol which often coexists in IP-based internets. This memo provides the mechanisms by which IP- based management stations can effectively manage DECnet Phase IV based systems (especially router products) in an integrated fashion through the use of the standard Internet SMI, MIB and Simple Network Management Protocol.
DECnet Phase IV objects have been defined to be used in conjunction with the Internet MIB to allow access and control of these new objects by the Internet community. Additional support for other DECnet-based protocols such as RBMS (remote bridge management software) or other Digital Equipment Corporation Specific Hardware platforms is not included in this document.
Selected Objects
The objects included in this memo have been created from the DIGITAL Network Architecture Network Management Functional Specification Version 4.0.0 Dated July 1983. An attempt has been made to provide a reasonable ordering of these variables into groups. These groups are:
o System Group
o Network Management Group
o Session Group
o End Group
o Routing Group
o Circuit Group
o DDCMP Group
o DDCMP Multipoint Control Group
o Ethernet Group
o Counters Group
o Adjacency Group
o Line Group
o Non Broadcast Line Group
o Area Group
An effort has also been made to preserve the original syntax of the object wherever possible, for example, a DECnet Phase IV object is Executor State. This was originally coded as a NICE (Network Information and Control Exchange) data type which is a Coded single field object of 1 byte in length. When converted for inclusion into the Internet MIB using the Internet SMI, it became an enumerated integer.
Objects
All objects in this memo are described using the standard Internet SMI and BER of RFC 1155. A complete description of an object will include the name, syntax and encoding. Just as with objects supported in the MIB (RFC 1156), an object name is identified with an object identifier which has been administratively assigned. This identifies an Object Type. When an object type is combined with a specific instance, the particular object is uniquely identified. The use of Object Descriptors in this memo is consistent with that of RFC 1156 - they are text strings meant to be read by humans. The descriptors have been taken from the original DIGITAL Network Architecture Network Management Functional Specification Version 4.0.0 Dated July 1983 which defined DECnet Phase IV objects. These names were then massaged to put them in a form as consistent as possible with object type names listed in the standard Internet MIB. Object defintion information is also taken directly from the Network Architecture Network Managment Functional Specification cited above wherever possible. In this document, EXECUTOR is intended to reference only the DECnet software and is not intended to effect any other protocols which may be running on the system.
Format of Definitions
An object in this memo is specified by five fields of information: Object, Syntax, Definition, Access, and Status.
The OBJECT is a textual name (OBJECT DESCRIPTOR) for that object type combined with an administratively obtained OBJECT IDENTIFIER.
SYNTAX: For each object type, its abstract syntax is presented using the ASN.1 specified in RFC 1155.
DEFINITION: A general description of the object type. Its original purpose in the DECnet Phase IV environment is given so that all implementers and users will consistently interpret the information contained in each object type. Changes in format to make the object consistent with RFC 1155 are also noted.
ACCESS: The standard access keywords supported in RFC 1156 are used. The keywords used in this MIB are: read-only, read-write, and, not- accessible.
STATUS: The status field is used to describe with a single keyword whether the object type is mandatory or optional. Status keywords of obsolete and deprecated are not used in this memo since this is the first version of the DECnet Phase IV MIB.
Textual Conventions
New datatypes have been introduced as a textual conventions in this DECnet Phase IV MIB document. The purpose of these additions is to facilitate understanding of new objects in this MIB. No changes to the SMI or the SNMP are necessary to support these conventions which are described in 4.0 (Object Definitions).

value of 6 is included to provide compatibility with
the parameter definition in Phase III, which included
the Routing overhead.) It does not include Routing or
Data link overhead (except for the constant value of
6). There is one buffer size for all circuits.
NOTE: The BUFFER SIZE defines the maximum size messages
that the Routing layer can forward. The SEGMENT BUFFER
SIZE (defined below) defines the maximum size messages
that the End Communication layer can transmit or
receive. The SEGMENT BUFFER SIZE is always less than
or equal to the BUFFER SIZE. Normally the two
parameters will be equal. They may be different to
allow the network manager to alter buffer sizes
on all nodes without interruption of service. They both
include an extra 6 bytes for compatibility with Phase
III."

allowed from the executor to any node within an area.
The path cost is the sum of the circuit costs along
a path between two nodes. This parameter defines the
point where the executor node's Routing routing
decision algorithm declares another node unreachable
because the cost of the least costly path to the
other node is excessive. For correct operation, this
parameter must not be less than the maximum path cost
of the network."

"This value represents the maximum number of routing hops
allowable from the executor to any other reachable node
within an area. (A hop is the logical distance over a
circuit between two adjacent nodes.) This parameter
defines the point where the executor node's Routing
routing decision algorithm declares another node
unreachable because the length of the shortest path
between the two nodes is too long. For correct
operation, this parameter must not be less than the
network diameter. (The network diameter is the
reachability distance between the two nodes of the
network having the greatest reachability distance,
where reachability distance is the length the shortest
path between a given pair of nodes.)"

DESCRIPTION
"This value represents the maximum number of nodes a
message coming into the executor node can have visited.
If the message is not for this node and the MAXIMUM
VISITS number is exceeded, the message is discarded.
The MAXIMUM VISITS parameter defines the point where
the packet lifetime control algorithm discards
a packet that has traversed too many nodes. For correct
operation, this parameter must not be less than the
maximum path length of the network. (The maximum path
length is the routing distance between the two nodes of
the network having the greatest routing distance, where
routing distance is the length of the least costly
path between a given pair of nodes.)"
